thanks for the link to the mymarkvision website. while their website is still under construction, i tried to reach them through their online form and asked if they have a formatting tool specifically made for their flash drives.

ill post here if i get updates from them via email.

meanwhile, i found this suggestion from a user that supposedly had a problem with a markvision flash drive.

in summary:
1. browse to KINGMAX Technology Inc.
2. download and extract the external hard drive software
3. Install and run the executable. Use it to format the markvision flash drive.

The tool is supposedly made by kingmax, but it has worked for non-kingmax branded flash drives.
